To all whom it may concern:

Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Typewhich the following is a specification.

This invention relates to, the paper-feedewgitin'g machines, and its object is to facilitate the roduction oi carbon or duplicate copies ot an original typewritten sheet, and particularly to provide means for making a carbon record, tally or duplicate of the prices or amounts entered upona succession of bills or invoices.

In the preferred form of my invention, 1 endless band of carbon paper or ribbon, inked only on one side. This endless band is passed around the platen, with the inked side toward the latter; and 1 provide meansto cooperate with the platen for and causing the latter to fcedaround the laten.

In the illustrated orm of the invention, I

provide two rolls remote from the platen,

overwhich said endless band is carried;

and between said rolls and the platen, I

mount a pairof paper reels, one towind and the other to pay out the paper, the latter being led from the delivery reel or spool down and around the plpgren within the inkup E A om the platen to The-platen, spools and all confinedwithin the endless The machine, being thus bill is introduce around the platen in the usual manner, with the price or amount columns on the bill overlying the inking band and record web; and then the Such prices and paper are a complete record or tally is obtained on the single tally strip of allot the transactions which have been typewr tten during the day upon a large number of bills.

. In the accompanying drawings, Figure 1 one form of my improvements as applied to the well kngwn 1g. 2 is a detail of a paper reel. Fig. 3 shows a fixed axle whereon the winding paper reel is detachably mounted. a illustrates deby springs 10,

finger lever .11 connected by a link 12 to a crank arm 13 formed upon a releasing shaft tails for detachably connecting the paper reel to its fixed axle.

Upon the front sid of a cylindrical platen 1,-revolubl mounte on a platen frame 2 and rotate by means of a hand wheel 3 or otherwise, strike types 4, carried upon type bars 5, which are operated by finger-keys in the usual manner.

Passing around one end of the platen, preferably the right-hand end, is-an endless band 6, inked as at 7 only upon its under or inner side, that is, the side next to the platen. Said band is of suitable length, and its upper end runs over a pair of idle rolls or'guide pulleys 8. The longitudinal movements of the band are effected by the rota- 7 tion of the platen, with which cooperates a set of pressure rolls, one whereof isseen at 9; said rolls being pres'sed against the platen and releasedat will by a 14. The rolls 8 preferably of soft rubber,

are loosely mounted upon studs 15 carried upon the upper end of a standard 16, which is fixed at its base to the righthand end of the platen' frame 2 and inclines upwardly,

and rearwardly therefrom. Flanges 15 for uidingthe band are fixed upon the studs fiy means of hubs 15. A. strip of record paper 17 is wound upon a delivery spool 18 and led thence downwardly and around the platen within the inking band 6, and then upwardly to a winding spool 19; so that during the rotation oi' the platen the paper may pay ofithe spool 18 and pass down around the platen and there be written upon and then up to become wound on'the spool 19, Said spools, which are supported upon the standard 16, itwill be seen are within the inking band 6, and between the idle rolls 8 and the platen; thewinding spool being above the delivery spool.

The paper is drawn ofi from the delivery spool by the rotation of the platen; said paper being pressed against the platen by the ressure roll 9. In order to enable the win ing spool 19 always to take up the paperstrip as fast asthe'latter is delivered from the platen, I connect the platen-by an endless cord 20 to a pulley '21, loose upon fixed axle or stud winding reel or'spool1'9; said cord fittin ina groove 22 formedin the 24 and connected to the eriphery o atom The diameter of t e pulley 21' 1 the platen, U'fl'iis tenl is only about one-third oil the diameter of the platen, so that the spool 19 tends to make three revolutions to one revolution oi? *ncy does not however result in a rupture o' the paper strip, since the'cord 520 may readily slip around the pulley 531 when the paper deliveied from. the platen becomes tout, the resu being; that the paper .is wound smoothly and tightly upon the spool. 19,

The spools or reels l8, 19 may be readily slipped oil? from their fixed axles each spool being provided "with a spring latch il secured upon the outside of the spool hub 28 and projecting Within slot 2'? formed tinnsversely through the Wall 075 the hub. Said spring detent niilspted to engage peripheral groove termed in the lined spool axle. The pulley 21 is provided with a pin 29 to engage a SO in the huh oil the spool 19, to cause the spool. to relate with. the pulley; and. this spool is also provided vith a paper hook 31 upon .1

In operation, the inking hand being suitably mounted, a full paper reel 18 is slipped upon the fixed sxle or stud 23, and the loading edge of the paper is carried first down from the spool and around the plate within the inking band (5. and then upwardly, and is caught upon the hook ill upon the hub of spool 19. .l."hen a hill or other sheet 352 is introduced. around the body oi the platen in the usual manner and written upon the tally strip devices being placed forward of the introductory side of the machine or in front of the usual paper shell (forming part of frame 2) to give clearance toperl'nit the main sheet or bill to overlap the telly strip; and such figures or charactors as are Written upon the righthand edge portion of the bill are duplicated by means ol'the inking band 6, upon the tally strip 17. It will be seen that as soon as one bill is finished. it may be readily withdrawn without rotating the platen, since a depression of the release key 11 throws oil the pressure rolls 9, to permit the Witl'idrsuml of said. bill,

Without however disturbing either the feeding hand or the record wel. 'lhen a new bill may be inserted and Written, and so on until the Web, which during the rotation of the platen Winds upon spool. .19, is exhausted. Then the spools may be withdrawn and fresh ones having new Web may be substituted. The platen is advanced line by line in the usual manner.

Variations may be resorted to Within the scope of my invention, and portions my improvements may he used without others.
